Looking for Advice on Selecting Trace Hardware and Software for RTEMS and Cortex-M

I didn't use the Lauterbach trace on this platform, but it is quite
useful in general. Lauterbach offers a low cost trace solution for Cortex-M:
They provide RTEMS awareness. Due to the instability of internal kernel
APIs, this usually requires some support from Lauterbach for your
current RTEMS version. This is normally done in a couple of work days.
